Applying the Standards: Math Workbook for first-grade offers 64 pages of targeted math practice. It is aligned with current state standards and includes a problem-solving rubric, standards alignment chart, and standard-specific pages of math problems and performance tasks. First-graders will be able to prove deep understanding of topics that range from numbers and counting, simple addition and subtraction, and measurement basics, to simple geometry. The Applying the Standards: Math series emphasizes higher-level thinking by requiring students to complete performance tasks to prove understanding of each standard. Grade-level math skills are covered, and a culminating reflection question for each performance task engages students in the standards of mathematical practice. Current state standards and depth of understanding are also emphasized through the series.
